چکیده
Background: Appendicitis is one of the most common abdominal emergency. Some predictive scoring systems are recommended to decrease the rate of negative appendectomy. Aim: To evaluate sensitivity, specificity, positive predictive value, and negative predictive value of modified Alvarado score in children who underwent appendectomy. Methods: Four hundred children with initial diagnosis of appendicitis were randomly selected from patients who underwent appendectomy. Modified Alvarado score was used for evaluation of the appendicitis, that was confirmed using histology. Results: Of modified Alvarado score components, anorexia; nausea and vomiting and rebound tenderness were significantly more common in children with positive appendectomy in contrast to patients with negative appendectomy. Sensitivity, specificity, positive predictive value, and negative predictive value for modified Alvarado score were: 91.3%; 38.4%; 87.7%; and 51.2% respectively. Conclusion: Alvarado score has high sensitivity but low specificity for diagnosis of acute appendicitis in children. Racional: A apendicite é uma das emergências abdominais mais comuns. Alguns sistemas de pontuação preditivos são recomendados para diminuir a taxa de apendicectomia negativa. Objetivo: Avaliar a sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo do escore de Alvarado modificado em crianças submetidas à apendicectomia. Métodos: Quatrocentos crianças com diagnóstico inicial de apendicite foram selecionadas aleatoriamente de pacientes submetidos à apendicectomia. A pontuação de Alvarado modificada foi utilizada para avaliação do quadro, que foi confirmado por meio de histologia. Resultados: Anorexia; náuseas, vômitos e desconforto abdominal foram significativamente mais comuns em crianças com apendicectomia positiva, em contraste com casos negativos pelo escore de Alvarado modificado. A sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo para o escore de Alvarado modificado foram: 91,3%; 38,4%; 87,7%; e 51,2%, respectivamente. Conclusão: O escore de Alvarado possui alta sensibilidade, mas baixa especificidade para o diagnóstico de apendicite aguda em crianças.
